"This is where it all began, New Hampshire - first victory," he said in a speech at the Atkinson Country Club. "In four days we are going to win the state of New Hampshire, and we are going to win back the White House... We're on the cusp of historic change."

Just a few weeks ago, Democratic nominee Hillary Clinton had a big lead in New Hampshire. But three new polls released Thursday now show the two candidates in a virtual dead heat.

Clinton will be in New Hampshire on Sunday, and President Barack Obama will attend a rally for Clinton at the University of New Hampshire in Durham on Monday.

Trump and running mate Mike Pence will also be in the critical swing state on Monday night for a rally at Southern New Hampshire University.

Trump mostly stuck to his usual talking points on Friday, hitting Clinton over the FBI's investigation of her emails, saying Obamacare needs to be recalled immediately and promising that, if elected, he will build "a great wall" to keep out illegal immigrants.
